A Hillary Clinton TV ad claims that “in the last seven years drug prices have doubled.” A report, provided by her campaign, says brand-name drug prices on average have more than doubled. But more than 80 percent of filled prescriptions are generic drugs.

Sen. Bernie Sanders claims that in the United States, “almost all of the wealth rests in the hands of the few.” He exaggerates. At most, the top 0.1 percent of U.S. families own 22 percent of the nation’s wealth.
